Answer 2

The first integer with which we are supposed to start is 3.

We are now supposed to subtract 10 from 3.

On subtraction,we get:

3-10=-7.

So now,we got another integer -7.

We are supposed to subbtract 1 from -7.

On subtraction,we get:

-7-1=-8.

We now got another integer -8.

We are supposed to multiply -8 with -3.

On multiplication,we get:

(-8)*(-3)=24.(- * - = +).

Now, on subtracting 20 from 24, we will get:

24-20=4.

We got the. final answer as 4.

This can be written as:

(((3-10)-1)*-3)-20=4.
